Raadi manor located near Tartu stood out from the others with its rick art collection and library and lounge evenings. Several generations of the manor owners von Lipharts were significant middlemen of the University of Tartu and other educated Baltic-German circles and the nobles of Saint Petersburg. The first half of the 19th century can be considered the glorious era or Raadi, when communication with renowned musicians and art people was tight. Maria Fjodorovna, the wife of czar Paul I was also enraptured by Raadi manor park.
The end of the 19th century and the beginning of the 20th century can be considered the deterioration era of the Baltic-German manor culture. The fact that it was relatively closed was probably one of the reasons for the degeneration. The same tendency is also visible regarding Raadi manor: the former sense of style was lost – for example, the castle was significantly rebuilt during the turn of the century without considering the former characteristics.
The Lipharts left Estonia during World War I and later took the most valuable part of their collection away. The University of Tartu took possession of the manor. During 1922-1944, it was in the possession of the Estonian National Museum.
In the autumn of 1940, over 100 ha of Raadi manor land was taken to expand the airport of the Soviet Union, in 1944, the castle caught fire during bombing.
